OOPS !!   completely misread your code, should that elif be an else?

Try this:

                        if not self.listOfObjects:
                                self.listOfObjects.append(self.currentObject
)
                               #or:  self.listOfObjects = list(
self.currentObject)
                        elif  self.listOfObjects[self.currentSlice] =
self.currentObject :
                                do something
                        else:
